Polyethylene terephthalate-graphene nanocomposites
A nanocomposite material comprises polyethylene terephthalate (PET) as a base polymer and a nanoparticle that increases the strength of the base polymer.
1. A nanocomposite material comprising:
a polyethylene terephthalate base polymer; and
exfoliated graphene nanoplatelets compounded with said polyethylene terephthalate base polymer to increase strength of the polyethylene terephthalate base polymer, wherein said exfoliated graphene nanoplatelets are present between about two percent and fifteen percent by weight of the nanocomposite material.
2. The material of claim 1 , wherein the nanocomposite material comprises about two percent by weight of the exfoliated graphene nanoplatelets.
3. The material of claim 1 , wherein the nanocomposite material comprises about five percent by weight of the exfoliated graphene nanoplatelets.
4. The material of claim 1 , wherein the nanocomposite material comprises about ten percent by weight of the exfoliated graphene nanoplatelets.
5. The material of claim 1 , wherein the nanocomposite material comprises about 15 percent by weight of the exfoliated graphene nanoplatelets.
6. A method of producing masterbatch pellets, the method comprising:
providing a polyethylene terephthalate base polymer;
providing between about two percent and fifteen percent by weight exfoliated graphene nanoplatelets;
compounding the polyethylene terephthalate base polymer with the exfoliated graphene nanoplatelets so as to obtain exfoliated graphene nanoplatelets dispersed in the polyethylene terephthalate base polymer; and, forming masterbatch pellets from the exfoliated graphene nanoplatelets dispersed in the polyethylene terephthalate base polymer.
